"Fig. 5 isasimilar view of the clamp disk,E, with which it is connected bylongiing'andtw-isting mechanism. Fig. 6 is an entudinal splines c, whichadmit of the arbor being moved lengthwise. The wheel E is provided, asshown in Fig. 12, on its rear side with" pivoted pawls d, arranged toengage with corresponding ratchet-teeth formed upon a wheel, a, securedto a bevel-pinion, j, which loosely encircles the arbor. This connectionpermits the pinion f to revolve in one direction loosely upon the arbor,but causes it, when revolved in the opposite direction, to impart motionthrough the pawls and ratchet-wheel to the arbor. The bevel-pinion freceives an interinitting rotary motion from corresponding bevel-teethextending partially around the periphery of the wheel F, mounted on ahorizontal axis. This wheel receives an intermittent rotary motion inopposite directions, as will be hereinafter explained, and, by means ofconnections above described, it consequently imparts to the tubulararbor an intermittent ro- 'tary motion always in the one direction, as

above referred to.

For the purpose of feeding the main wires ('1 forward through the arborwith an interniitting motion, I locate'in rear of the arbora pair ofhorizontal feed-rolls, G G, between which the wires pass, and thence tothe arbor. The lower roll, G, is provided at one end with 1t loosespur-pinion, H, having a pawlandratchet connection, a, therewith, asrepresented in the drawings, Figs. 17, 18. The spur-wheel H is arrangedto engage with and receive motion from corresponding spur-teeth formedon the edge of the before-mentioned wheel F, this wheel having, as willbe observed, the bevel-teeth upon one portion of its periphery, and thespur-teeth upon the other. The arrangement of the ratchet mechanism forrotating the arbor and that for rotating the feed rolls is such thatwhen the wheel F is turned in one direction it will impart a rotarymotion to the arbor and permit .thefeed-rolls to remain at rest, andthat when revolved in the opposite direction it will permit the arbor toremain at rest and revolve the feed-rolls, causing the wires to beadvanced through the stationary arbor. The reverse rotation of thefeed-rolls is prevented by a pawl and ratchet, a, as clearly representedin Figs. 1, 17, and 19.

Passing now to the means for applying the barbs, the forward end of therotary arbor is provided with a coiling-head, A, such as represented inFig. 13, which revolves therewith. This head has the central opening,through which the extended ends of the main wires emerge from the arbor,and is provided in its front face'with four radial or substantiallyradial grooves, i, to receive the barb-wires I and admit of their beingprojected transversely across or between the main wires, as shown. Theeoiling-head is encircled by a peripheral flange, J provided with holesor openings b, coincident with the outer ends of the grooves i. Theseholes are designed to receive and guide the ends of the barb-wires, andto retain the same in position during the operation of coiling themabout the main wires and until the twisting operation is completed. Thegrooves or slots 43, through which the barb-wires are introduced, havean inclination forward in the direction of the axis of the arbor fromthe outer edge toward the center, for the purpose of causing the twobarb-wires which enter from opposite sides to pass obliquely across eachother and across the main wires, instead of lying, as they wouldotherwise do, parallel with each other and at right angles to the mainwires. This introduction of the barb-wires at a forward inclination alsocauses their. inner ends to be projected in front of the face of thehead in such manner that they may be held by the gripping. or clampingjaws hereinafter explained. This construction of the grooves and themanner in which the barb-wires are introduced at different angles areplainly represent ed in Fig. 1, the course of the wire being indicatedin the figure by dotted lines. resented in the drawings, the grooves 'iin the face of the coiling-head are made of a depth greater than "halfthe diameter of the wires, so that there will be no tendency on the partof the wires to ride out of the grooves while the head is in motion. Asa result of this construction, I am enabled to operate the machinewithout the employment of movable jaws or devices to retain. the wireswithin the grooves of the coiling-head. The barb-wires are coiled upontwo rolls, K, mounted one upon each side of the machine, as representedin the ures. From these rolls the wires pass between feed-rolls L, whichwill be presently described, and thence through holes or guides formedin a stationary head block, hi, this stationary head-block serving toguide the ends of the barb-wires with certainty and accuracy into theperipheral openings of the coiling-head during the time that the latteris at rest.

The feeding of the respective barb-wires inward at the proper times andto the proper extent is accomplished by means of the two pairs offeed-rolls L, before referred to. These rolls are mounted on horizontalshafts or bearings,

one pair at each side of the machine, and are made adjustable as topressure and driven in termittingly by means which will be hereinafterdetailed. After the barb-wires have been projected inward across themain wires, it is necessary that the portion to form the barb shall besevered from the main wire, and that each of these severed portionsshall be firmly held at one end while the opposite end is being coiledaround the main wires by the rotation of the coiling-head. For thepurpose of retaining the ends of said wires I employ two pivotedclamping or gripping jaws, N, pivoted to and arranged to co-operate witha stationary anvil, O, as plainly represented in Figs. 1, 3, 16. Theanvil-block O is provided with a central groove, m, to permit thepassage of the main wires through the same, and with shouldersorbearingfaces n, upon which the ends of the barb-wires are clamped bythe jaws N. The clamping jaws or levers N are pref As repferred to.

erably sustained upon horizontal pivots passed through the anvil-block,as shown. The clamp ing-jaws are adapted to act uponthe upper surfacesof the anvil by having their upper ends or jaws proper projectedlaterally to engage over the anvil, as shown in Figs. 9 and 16. The jawsor grippers are caused to act intermittingly by means which will behereinafter explained. The active ends of the jaws or grippers and theanvils with which they cooperate are arranged immediately in frontof thecoiling-head in such position as to grip the wires at a point within theline of its periphery, as shown. a

Referring next to the means for effecting the severance of therespective barb-wires, the same will be found to consist of ,two pivotedeuttinglevers, P, mounted on horizontal pivots in' front of theclampingjaws, each h: ving a blade arranged to co-operate with acorresponding stationary blade, Q, secured in the face of the stationaryheadblock M, before re- Each of the lcversl has its cuttingblade, 12,secured therein by means ofa set-v screw, q, or equivalent deviee, whichwill admit of its adjustment or removal at will. The

. stationary cutting blades Q are seated in grooves in the face of thefixed head-block, and secured by means of screws,,as shown, or. othersuitable devices which will admit of their being also adjustedandremoved at will. The cutters swing in planes at right angles orsubstantially right angles to theaxis of the main wires, in a directionoblique to that in which the barb-wires are extended, so that in actingupon said barb-wires theyshear or sever the same obliquely, thusproducing sharp points upon. the barb-sections The operation of theparts above enume ated is as follows: .The main wires are extendedthrough the arborand the head, as before described. The arbor standingat rest, the feedrolls G- and G cause the main wires to be advanced asuitable distance, after which the rolls cease their motion. Thebarb-feeding rolls L are operated at the same time and caused to project thebarb wires inward through the peripheral openings and the radialslots inthe coiling-head until said wires cross the main wires and each other,and until their inner ends are brought over the faces 1 of the anvils O,whereupon the feed-rolls L cease their motion. The clamping jaws orgrippers N then descend and hold the inner ends of the barb wires firmlyin place upon the anvils. The cutting-levers P next swing downward attheir upper ends and effect theseverance of the barb-wires,removing fromthe in ner end of each a piece of sufficient length to forma singlebarb. At this point in theoperation the severed barb-sections lie acrossthe main; wires and across each other in the grooves of thecoiling-head, their outer ends projecting from the peripheral openingsof the head; and their inner ends beingheldrigidly by the clampingdevices, the other parts being at rest. The coiling-head now commencesits rotation around the main wires, which remain at rest, carrying withit the outer ends of the barb-wires, which are thus firmly coiled aboutthe main wires. By the ceiling operationthe barb -wires are reduced inlength and their outer ends gradually drawn inward, until finally theyare drawn through the peripheral. openings of the head into the slots,whereupon the rotation of the coiling-head ceases. The outer ends of thecompleted barbs are now free, so that they may be carried forward withthe main wires, which are immediately caused to advance, by the actionof the feed-rolls G G, a sutlicient distance to permit the applicationof the succeeding barb, after which. the operations above described areagain repeated.

Inasmuch as the barbs are held firmly at one end during the coilingoperation, they are wound backward upon the main. wire, and, if noprovision were made to the contrary, would crowd or bind against theface of the coilinghead. It is to guard against this contingency thatthe longitudinal motion of the coilinghead and the arborbefore referredto are permitted. A strong spring, R, secured to the frame and bearingagainst the rear end of the arbor, as shown in Figs. 9 and 11, mrges'thesame with its coiling-head forward. The yielding of the spring permitsthe head to -movegradually backward under the pressure of the wirecoiled against its front face.

Passing now to the details of the mechanism by which the motion isimparted to the devices above described, it will be seen on refer- U,pivoted to an arm, c,on rod 7/, as plainly j represented in Fig. 8. Thearm U is connected by an intermediate swiveling joint with a pitman, V,the upper end of which is in turn connected by a i'mivcrsal joint orswiveling connection with the geanwheel F, before alluded to. Thisconnection consists, as shown in Fig. l, of a block, I), having at rightan gles to each other two journals or wrists, one of which passesthrough the upper end of the pitman, while the other passes, as shown indotted lines, through the wheel F. The rotation of the crank-shaftcauses a reciprocating motion to be imparted through the pitman V to thewheel F, giving the lattera partial rothe Imain wiresstationarydnringthe opera; tion of gripping and'severing the barb-wires.

For the purpose of imparting motion to the cutting-levers P, I connecttheir lower ends, as shown in Fig. 4, by means of two links, WV, whichare in turn connected at their adjoining ends by means of areciprocating rod, X, to a forked lever, Y, mounted on rod 12 and actedupon by a double cam, Z, on the main shaft. The rotation of the camcauses the lever Y to move upward, lifting the inner ends of the links"W and causing them to actuate the levers l in such manner as to throwthe knives backward out of action. At the proper time, however, the cam,acting upon the lower end of the lever Y, depresses said lever, causingthe links \V to assume the position indicated by dotted lines in. Fig.4., and thereby .cause the operation of the cutters. To insure a properaction of the rod X upon the links WV, the upper end of the rod ispreferably guided by passing it through an opening in the bedplate, asshown in Fig. 4. 1

Passing next to the devices for operating the clampingjaws N, it will beseen that the lower ends of the cam and levers are connected by links toa reciprocating rod, X, and to a le ver, Y, mounted on rod b, andactuated by a double cam, Z, on the main shaft, the general constructionbeing similar to that for operating the cutters, the form of the camsbeing, however, modified as required. In order that the jaws may actwithayielding pressure upon the wire, so as to confine the same firmlywithout danger of its being crushed, I interpose, v

as shown in Fig. 7, between lever Y and the rod X a spiralcompression-spring, forming a connection between the two, as plainlyrepresented. This spring, yielding in the event of an excessive strainbeing applied, prevents the jaws from acting with dangerous pressure.The double cams and the crank upon the main shaft are so adjusted withrespect to each other as to cause the operation of the various parts inthe order hereinbefore recited.

In order to insure the firm engagement of the feedrolls with the wire, Iprefer to construct'them in the manner represented in Fig. 14, each rollconsisting of a central hub or body, a, and of a peripheral band or ringof soft steel, b, shrunk or otherwise firmly secured thereon, the bandbeing provided with a series of fine circumferential grooves, as shown.This construction is also advantageous in that it admits of thewearing-surfaces being removed and renewed when worn.

The lower feed-rolls, L, by which the barbwires are advanced, aremounted upon horizontal shafts d, the rear ends ofwhieh are providedwith bevel-pinions c, driven bycorresponding pinions,f, applied to theshaft of the main feed-roll G, as shown in Figs. 1 and 2, whereby thevarious feed-rolls are caused to move in unison, and thus advance themain'and barb wires simultaneously. The upper rolls, L, for feeding thebarb-wire are mounted on vertically-swinging arms subjected to thepressure of screws k acting ,on. springs Z,-

whereby the roll may be adjusted to act with any required degree ofpressure upon the wire. The main feed-roll G is in like manner depressedby means of screws m passing through a supporting-spring, a, and actingupon the bearings of the rolls.

To insure a firm hold of the clamping-jaws upon the wire, I prefer toarm each jaw with a soft-steel facing, p, as shown in Figs. 6 and 6",secured by a screw and removable at will.

The reels upon which the wire is wound are each constructed in themanner represented in Figsrl and 20. A circular plate or disk, (1',forms the base of the reel and gives support to a cylindrical hoop orbarrel, 0, of

smaller diameter, seated thereon. The hoop in journal projects above thesurface of the reel,

and is provided with a spiral spring, 2", bearing at its lower end ontop of the reel and at its upper end beneath a collar applied to theupper end of the reel-spindle. The spring thus applied, acting jointlywith the elasticity of the arms f serves to produce sufficient frictionto give the required tension to the wire. The construction of the reelsin the particular manner described is advantageous on account ofitssimplicity and cheapness, of the fact that it exposes the wire to viewin such manner that the operator may readily perceive in advance thefact that the supply is nearly eX- hausted, and of the facility which itaffords for securing the end of the wire.

Referring again to the stationary dividing strip employed as within therotary arbor to separate the main wires, attention is directed to thefact that the rear fixed end of this strip is twisted or given aquarter-turn about its axis. As the two main wires emerge from thefeeding-rolls G and G they lie side by side in the same horizontalplane; but by reason of the twist in the end of the dividing-strip justdescribed the position of the wires is changed, so that they lie oneabove the other in passing through the arbor, this changed position ofthe wires facilitating the application of the barbs thereto. 1

Referring again to the coiling-head and its action in winding the barbsupon themain wire, it is found in practice that the barbs, after beingcoiled, have a slight tendency, owing to the elasticity of the wire, toreact or unwind from the main wire. To avoid the loosening of the barbsby this action, we find it desirable to give the coiling-headaslightly-- increased rotation, so as to carry the points slightlybeyondthe point at which they are expected to stand, in order that they mayreact to the proper point. This additional forward rotation of the headis secured by applying to the main driving-wheel F an eccentric arm orprojection, on, as plainly represented in Figs. 1, 2, and 9. This arm,acting upon the ratchet-wheel applied to the arbor which carries thetwister-head, servesto turn said wheel and thereby the twister-headslightly beyond the position to which it would be carried by the gear.The reactionary motion of the coilinghead is limited and the headstopped at the proper point by, means of a pawl, engaging with aratchet-wheel, c, secured to the arbor,

as represented in Figs. 1, 9, 10, 11, and 12.
